Study on Water Structure Change Rule Based on Information Entropy Perspective

摘要

This article analyzed the evolution rule of the water use structure in recent years in China based on the information entropy. It is found that water structure tends to disorder, water system equilibrium degree increases, single water trend becomes weak, and water system tends to be complex and stable. The water use structure goes through the process of "orderly but low efficiency " to" disorderly "to" orderly and high efficiency" and presents the form of inverted "U". This study used prediction model of composition data. The predicted proportion of the non-agricultural water will be at 41.1% in 2026. The information entropy and equilibrium degree is growing. Finally, the government should increase the water use for ecological, adjust the water use structure and promote the industrial structure up-grade.
